THOMAS SHEPPARD BAEWIS, OF VANCOUVER, BRITISH COLUMBIA, CANADA, ASSIGNOROF ONE-HALF TO FREDERICK OOATE'WADE, OF VANCOUVER, CANADA.

MARINE VESSEL.

Specification of Letters Patent.

Patented Sept. 3, 1907.

To all whom it may concern:

Be it known that I, THOMAS SHEPPARD BARWIS, a subject of the King ofGreat Britain, and a resident of Vancouver, in the Province of BritishColumbia and '5 Dominion of Canada, have invented certain new and usefulImprovements in Marine Vessels, of which the following is a full, clear,and exact description.

My invention relates to marine vessels, and has for its principal objectto provide a marine vessel with a floatable cabin or deck, which fits inthe vessel and is held there solely by gravity, so that it may float outshould the vessel founder.

Another object of the invention is to support the sides of the cabin ordeck on gussets, with passages thereunder, so that it'will be rigid onthe vessel when it floats and will also make possible the easy flotationof the cabin or deck should the vessel sink.

One embodiment of the invention is shown in the accompanying drawingsforming a part of this application, which embodiment is described inthis specification. However I do not limit myself thereto as I considermyself entitled to all embodiments and forms of the invention which mayfall within the scope of the appended claims.

Figure 1 is a view of the vessel athwartships, partly in section; andFig. 2 is a broadside view on a smaller scale, which is also partly insection to show the invention.

Like characters of reference designate corresponding parts in bothviews.

A represents the vessel on which the floatable cabin or deck B issupported. The floatable cabin or deck B is preferably supported at itsbottom on a deck 0 which is rigidly and permanently secured to the ves-3 sol. This deck is flat and offers a satisfactory support iorthefloatable deck B which is secured in place while the vessel floats, bythe gussets D disposed between the floatable cabin or deck B and thebody of the vessel to which they are secured. At each side of the 40vessel is preferably arranged a passage E which is enlarged byconstructing the sides of the floatable cabin or deck obliquely anddownwardly as at F, from its roof until the gussets are passed, when itis extended horizontally and inwardly as at G a distance to pro- 4 videa suitable width for the passage E when it is built perpendicular as atH, to its base I which rests on the permanent horizontal deck O. Thefore and aft ends of the floating cabin or deck have the oblique portionF, but it is unnecessary to build the floatable cabin or deck to providefor the passage fore and aft, as the floatable cabin or deck does notextend to the bow or the stern of the vessel and there is ample roomwithout encroaching on. the floor space of the floatable cabin or deck.The passages E at the sides of the floatable cabin or deck and thespaces K fore and aft of it, may be used for the passage of the membersof the crew, but they are also provided with the view to prevent suctionwhen the vessel sinks and thus to increase the buoyancy of the floatablecabin or deck. Enlarged ports may be built in the sides of the vessel,which when opened will quickly flood the passages E and K, floating thecabin or deck as the vessel sinks and before the water would otherwisereach the passages E and K from below, early enough to release thefloatable cabin or deck. It is obvious that the floatable cabin or deckmay be built to save the mails and valuables as well as passengers andmembers of the crew, and that it can be arranged with companion ways,berths, etc., as may be deemed to be best in each case. On thefoundering of the vessel the water floats the floatable cabin ordeckfree from the vessel, thus permitting the passengers, crew, mails andmerchandise with which the floatable cabin or deck is loaded, to besaved.

Having thus described my invention I claim as new, and desire to secureby Letters Patent:

1. A marine vessel provided with a deck, a floatable cabin resting onthe deck, the said floatable cabin having sides and ends inclineddownwardly and inwardly for a distance, the sides of the floatable cabinbeing built inwardly below the inclined portion to form passage-waysbetween the floatable cabin and the sides of the vessel; and gussets onthe vessel, which are adapted to fit the tumbled in sides and ends ofthe floatable cabin.

2. A marine vessel, provided with a deck and side walls, a floatablecabin resting on the deck, the said floatable cabin extendingfrom wallto wall at its top and havingsides inclined downwardly and inwardly fora distance, the said sides of the floatable cabin being built inwardlybelow the inclined portions to form passage ways between the floatablecabin and the side walls, and gussets on the side walls which areadapted to fit the inclined side of the floatable cabin.

3. A marine vessel, provided with a deck and side walls, a floatablecabin, the said floatable cabin extending from wall to wall and havingsides inclined downwardly and inwardly for a distance, the said sides ofthe floatable cabin being built inwardly below the inclined portions toform passageways between the floatable cabin and the side walls, andgussets on the side walls which are adapted to fit the inclined sides ofthe floatable cabin.

4. A marine vessel, provided with a deck and side walls, a floatablecabin, the said floatable cabin extending from wall to wall and havingsides inclined downwardly and inwardly for a distance, the said sides ofthe floatable cabin being built inwardly below the inclined portions toform passage-ways between the floatable cabin and the side walls, andmeans to support the floatable cabin on the side walls.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

THOMAS SHEPPARD BARWIS.
